Why Is Quality Lead Flashing Essential for Your Roof?

Lead is one of the oldest and most reliable roofing materials used in the UK. It is primarily used to seal the junctions where your roof meets a wall, chimney, or another roof slope. Because these junctions are the most vulnerable parts of your roof structure, poorly installed or degraded flashing is a leading cause of water ingress.Common areas that rely on professional leadwork include chimney flashings, roof valleys, dormer cheeks, and step or apron flashings. When lead becomes thin, splits, or slips out of place, it leaves your property exposed to severe weather.Catching these issues early through professional roof leak detection can save you from extensive internal damage and costly structural repairs.

Frequently Asked Questions About Lead Flashing

How do I know if my roof flashing needs replacing?The most obvious signs are damp patches on your ceilings or walls, particularly near chimney breasts or directly under roof valleys. If you spot cracked, slipped, or missing leadwork from the ground, it is time to call a professional.Can lead flashing be repaired, or must it be replaced?Minor splits can sometimes be temporarily repaired using specialist lead welding techniques. However, if the lead is severely degraded, thinned, or no longer dressed correctly, a full replacement is the safest and most cost-effective long-term solution.Is lead still the best material for roof flashing?Yes.

Leadwork & Flashing FAQs

Frequently Asked Questions

Answers to common questions about our specialist leadwork, chimney flashing, and roof repair services from the experts at Kevington Roofing and Building LTD across Swanley, Sevenoaks, Kent, and Croydon & South London.

How do I know if my chimney flashing needs repairing?

+

The most common sign is water staining on the ceiling or walls around your chimney breast. You might also see visible gaps where the metal has pulled away from the brickwork, or find small pieces of mortar on the ground that have fallen from the flashing joints. If you are unsure, we can perform a quick drone survey to check the condition safely.

Can’t I just use bitumen tape to fix a leaking lead valley?

+

Flash-band or bitumen tapes are only temporary patches. They struggle with the expansion and contraction of the roof and usually fail within a few months. For a permanent fix in the Swanley area, we always recommend replacing the failed section with new, correctly weighted lead that is properly bossed and fixed.

How long does it take to replace lead flashing on a standard house?

+

Most flashing repairs, such as around a single chimney stack or a porch, can be completed within a single day. Larger projects, like replacing long lead valleys or installing a lead flat roof, may take two to three days. We always aim to keep your home watertight throughout the entire process.

Is lead theft a problem in Kent and how can you prevent it?

+

While lead theft can happen, we can use specific fixing methods and high-quality adhesives to make it much harder to remove. For high-risk areas, we can also discuss modern "lead-alternative" products that have no scrap value but offer similar waterproofing performance, though traditional lead remains the gold standard for longevity.
